Answers
Length = 8 m 50 cm = 850 cm
Breadth = 6 m 75 cm = 675 cm
Height = 4 m 50 cm = 450 cm
Length of the longest rod.
HCF of given dimensions
we have to find the HCF of 825, 675 and 450 .
825 = 5 × 5 × 3 × 11
675 = 5 × 5 × 3 × 3 × 3
450 = 2 × 3 × 3 × 5 × 5
HCF = 5 × 5 × 3
HCF = 75 cm.
Hence, the length of the longest rod which can measure the three dimensions of the room exactly is 75 cm.
